Well,I've got Win 7 Pro RTM installed on my Pentium 4 3 gig,2 gig ram,ati x1650 pro agp video,and asus p4s800dx mobo,and I love it!! I've got the theme i've been waiting for (basic black) and restart time from shutdown to desktop in 55 seconds! It runs great,games perform well,and it does everything I need it for!! I still have XP installed in a dual-boot config just in case but so far i've been using 7 as the primary os,and will continue to do so. The only thing i take issue with is everyone saying that win 7 boots faster than vista or xp! While it may be faster than vista,my xp config boots in 18 seconds,while 7 boots in approximately 35-40 seconds or 55 seconds if you go from shutdown to desktop,as i said earlier. So I think it is a very well made,and great fun to use os. Thank you. P.S:As others have said,this is what vista should have been,and let's face it,sooner or later xp will be gone,and i'm not into linux that much,and i'm definitely not a mac fan! (no offense to mac users) Just my view.
